I'm trying to separate two jQuery galleries, so they don't interlink on my html page:

http://mashanova.com/myFAQ/faqGallery.html#

here is the html:

here is javascript:

$(document).ready(function(){

$('.gallery_thumbnails a').click(function(e){

    e.preventDefault();


    $('.gallery_thumbnails a').removeClass('selected');
    $('.gallery_thumbnails a').children().css('opacity','1');

    $(this).addClass('selected');
    $(this).children().css('opacity','.4');



    var photo_fullsize = $(this).attr('href');
    var photo_preveiw = photo_fullsize.replace('fullsize','preview');


    $('.gallery_preview').html('<a href="'+photo_fullsize+'" style="background-image:url('+photo_preveiw+');"></a>');


    });

});
